Paper Title:
Numerical Study on Transient Heat Transfer in a Regenerative Oxidation Bed during the Preheating Process
  Abstract

The transient heat transfer characteristics of a regenerative oxidation bed placed in a coal mine methane thermal reverse-flow reactor during preheating process are numerically investigated in this paper. The regenerative oxidation bed is modeled in a three-dimensional, unsteady state and laminar flow system, and is assumed as a semitransparent porous media. The calculating results indicate that increasing the inlet mass flow could shorten the time of preheating, specific heat and porosity have a great influence on the heat storage capacity of the regenerative oxidation bed, and the contribution of the solid phase radiation to heat transfer can not be ignored. All these work can help to understand the heat transfer phenomena and mechanism in a regenerative oxidation bed during the preheating process.
